The Garmin Forerunner 945 is one of the best waterproof fitness trackers for swimming. It is one of the few watches that can correctly monitor heart rate underwater, making it a perfect addition for serious heart rate training because it can detect changes more quickly than a sensor on your wrist.

Additionally, it has a built-in audio player, so you can use a set of waterproof headphones to listen to your favorite tunes while swimming. It also offers various monitoring functions specifically designed for swimming, such as distance (with GPS monitoring), pace, stroke count/rate, the stroke distance and efficiency, and calories burned.

There are even more options for pool sessions, including drill logging, auto rest, stroke type identification, pacing alerts, and customized pool workouts (which can be downloaded to the watch over Wi-Fi).

Other features include safety and tracking, sleep score and advanced sleep monitoring, Livetrack, smart notifications, women’s health tracking, and more.

A robust multi-sports watch like the Coros Vertix 2 is an excellent option for swimming, especially if you’re going on vacation and won’t be able to charge it frequently. Whether you’re on foot, on a bike, or in the water, the Vertix 2 can maintain tracking for up to 140 hours with GPS enabled or 240 in Ultramax mode (or all three, with the multi-sport triathlon mode).

The 1.48-inch always-on display is large, clear, and high resolution, making it easy to monitor your training stats quickly.

How to Pick the Best Waterproof Fitness Trackers For Swimming: Step by Step

When shopping for a waterproof fitness tracker for swimming, you want to ensure you are getting one that matches the functions and capabilities you need, keeps you motivated, and checks all the swimming metrics. The key factors to consider include:

  • Water Resistance,
  • Battery Life,
  • Additional Features,
  • Design and Comfort,
  • Pricing.

Let’s look at each one in more detail.

Water Resistance

Since the watch will mostly operate in water, you need one that can withstand the water pressure. Different fitness watches have different water resistance ratings, so be keen to check. Some can handle shallow depths, while others are designed for deeper levels and are suitable for divers.

Most swimming fitness watches come with a water resistance rating of up to 5 ATM, meaning they can resist a pressure of 50 meters, while others are rated at 3 ATM, meaning they resist the pressure of 30 meters and should not be immersed in water.

Battery Life

When swimming, you want to be sure that your watch battery can last your swimming sessions without running out of juice. A long battery life ensures you capture all the swim metrics and monitor your progress, especially during training.

Look for a watch with a battery life of at least seven days or more when in use and, ideally, one that can last even longer in standby mode.

Additional Features

Every watch has different features unique to the model. As technology advances, manufacturers continually upgrade their offerings to meet the demand for comprehensive fitness trackers. For instance, the newest Apple Watch Ultra has significant improvements over the Series 8, such as extended battery life, a larger display, and a new Oceanic+ app ideal for diving.

If you want to monitor your heart rate, select a watch with heart rate monitors to track your heart rate while swimming and provide valuable data on your performance. Garmin Vivoactive 4 is well-rated for underwater heart rate monitoring.

Other features like sleep monitors allow you to monitor your sleep habits and give you helpful advice on getting a better night’s rest. Calendars allow you to schedule workouts and other events to stay organized and on top of your fitness goals.

GPS will enable you to track your route and distance, which can be useful for training and race planning. For comprehensive security, look for watches with fall and crash detection so they can withstand the falls of everyday use.

Design and Comfort

Swim watches come in all styles, materials, and features. You want a watch that is comfortable to wear for long periods in the water and can withstand the elements. You also want a fashionable design that complements your style and attitude. Some are made with robust aluminum casing and rubber straps that offer maximum comfort for long swim sessions.

Good-quality rubber straps are available in various unobtrusive styles that complement most casual and semi-casual outfits. They are entirely waterproof, dry rapidly, and prove incredibly soft and comfortable on the wrist. Rubber’s flexibility allows your wrist to be free for delicate underwater operations, making them very helpful for scuba divers.

Canvas and nylon bands are also options to consider. The face should be large enough to readily read the time and any other data you want to track while swimming. Backlights and digital displays, for example, can help ensure that the watch can be read even in low-light settings.


For most buyers, price is a key determinant of the fitness watches they choose. It is important to consider your budget and what features are important to you before making a purchase.

What to Know Before Buying a Waterproof Fitness Tracker

The first thing you need to know is the purpose of the watch. There is no need to go for the high-end models if you only need to measure your swim distance occasionally. However, if you are keen on training or watersports, you need a robust fitness watch to track vital swim metrics.

If you want to track other activities, such as running, cycling, and walking, ensure the look you go for has all those features. Ultimately, your needs come first before everything else. Write those down before you begin your search.

Using the Best Waterproof Fitness Trackers: What it’s Like

Using a waterproof fitness tracker for swimming can be rewarding and frustrating at the same time. Getting the right watch can feel like having an all-in-one personal trainer and coach on your wrist. You can easily track your swims with metrics like stroke rate, heart rate, calorie burn, and pool lengths.

Some smartwatches also let you access audio coaching or in-app workouts to get the most out of your swim. However, if the watch does not offer some of the features you need, not having all the information you need at the end of your swimming sessions can be frustrating. Other watches have poor displays, so you may not view notifications or emails.
